ABSTRACT:
An improvement in a method of extruding a plasticized powder mixture having a thermally gellable binder carried in an aqueous vehicle, by passing the mixture through an extruder and then through a die to produce an extrudate, the improvement being the additional step of contacting the extrudate directly after it leaves the die with an agent for simultaneously lowering the gel point of the binder and dehydrating the extrudate. The result is a stiffening of the extrudate in a shorter time than it would be, absent the additional step.
